So, I am having some problems to give a second life to this device.
I bought twice a battery to replace. The first one was clearly a second hand battery sold as new, which lasted 6 months, after which, it started to grow bigger in volume and its performance dropped dramatically lasting half an hour working. I tried to get a refund but no luck.
After that experience I tried a second seller who promises nothing less than 2 years warranty for the battery (wow). I bought a new original one and installed it. It seem in mint condition so I thought it would do it.
It worked everything aparently fine. I even installed a new custom room (i must admit that i am not sure if i did it right) But it appartenly worked. I had cRdroid with android 10 running smoothly on the phone. Not sure at this point if I rebooted after that. I think so.
The nightmare started once the battery ran out (I did it on purpose to calibrate de battery). The phone didn't wake up again. I started to have a blinking red notification led. It seemed not to be charging at all and indicating some problem with EDL mode or with very low battery. The fact is after trying long time charging, several chargers and cables, etc, i managed to get a yellow led light.
But what I can get by now is:
-if I plug a charger with a (sometimes) notification of a stuck 50% level of battery (wtf), sometimes bootloop, sometimes black screen
-Entering in fastboot mode with (vol- + power)
-Not able to enter recovery
-If I try to swich on it does not react to power button in any way.
I tried to flash all stock files by using xiaomimitool but it does not boot system afterthat (although i can get to stock recovery once at least after that)
i tried flashing twrp and it says ok installed but I cannot enter afterwards
and so on..
do i throw the phone away?
btw, it is unlocked and it is rn4 global sd version (mido)
I would have checked the battery voltage before flashing anything.
For me, I would have also taken the old, dead battery and used the the BMS PCB and connector off that and a bench power supply to power it up as a check.

Hello (a bit late).
I find this to be something that I should have done more than a solution now the problem is here. Even tough I don't properly understand your proposition and I find I might not possess the tools that you explain.
I never though that replacing a battery would bring this problems.
I managed to bring back to life the battery. Now is working without problems, but only because I am avoiding the phone from completely discharge the battery and I am charging it before it dies. Otherwise I have the feeling that battery will go under voltage again.
Is there something I can do to avoid this? I have checked voltage with some app and lectures seem to be normal while its working: 4.38 v and going down while it discharges. I do not have the old battery.

I was flashing a new rom. And after it said 100% on the phone it turned black and never lit up again. I waited i didnt pull out the usb. 15 min later i checked it again still black. i pulled the usb out. hit the power button and nothing happend. i did a hard reset and still the phone wount power on. The phone's charging led light wount even come on when i plug it up. So i assume i have bricked me phone ?
I have HSPL3
miri19v
froyostone 3.1v
is there any way to bring it back to life or do i toss it in the trash?
thanks for the help
i have also tried to go into boot loader and NIL!
from your use of the word 'trash' can i assume you have a tmous hd2? if so, what did you flash? was it a non tmous stock rom (meaning a bad radio)?
(oh, first job tho, check for bent battery pins)
the pins are fine. yeah i was actually flashing a stock tmou rom.
got the full filename for the rom you downloaded please? (just checking you havent downloaded a t mobile rom that isnt tmous)
the reason im pushing that line of enquiry is that the symptoms you describe are consistent with either
wrong radio (from the wrong stock rom)
bent battery pin
over discharged battery
to test the over discharged battery you can take it out, plug usb in with wall charger, then put battery in. this lets it charge without trying to turn on the phone. the light may not come one for some time, so leave it a good hour or two.
Hey Sam,
I'm having this issue too. I am relatively positive it's from an over-discharged battery. The phone conked out a few nights ago, and later when trying to charge it I got nothing - until yanking the battery for a bit, plugging in the charger, then popping in the battery. Now, every time the battery drains I have to do this.
Is the battery "damaged" now, or do you have any suggestions to fix the prob? I see this posted a bit but no one has any solutions that I've found.
Thanks!
Ryan
well i know the principals of these batteries, but not really the mechanics, so yes id guess the battery is defective, (but it could be the phones internal battery control circuits too, again just guessing) but no i dont know if there is a cure, other than try another battery, and if it cures it, ok, but if not then it would be a warranty issue.
are you using android? cos from what ive read it discharges quickly under android or something? (never used it so cant tell)
Hi,
Few days ago I forgot to reload the battery. Now that I try to bootup the gt-9100 it only shows battery logo with loading sign. It won't react to any button presses, so i can't get to download mode or to recovery mode.
I flashed CyanogenMod 9 Nightly a week ago. It worked like charm until now.
Does some one here have any kind of suggestions I could try?
Thanks..
How can you be sure that the battery has enough energy to boot the phone as you can still see that it is charging? Eventually the battery should be reported as fully charged.
when it depleted i connected it to charger and left it there to a whole night.
it should have enough charge.
just tested some some key combinations and i got good results. when i push vol down + home + power before i put battery back to the phone, i get to the odin mode.
now i have to find usb cable somewhere.
I got it flash new rom to it. First time the problem still persisted.
After trying some new button combinations and after flashing cmw i got it boot up.
Few seconds after fully booted, it powered off and i got same battery logo that does nothing. I'm starting to wonder that the problem is somewhere in the battery or the battery charger system.
Yes, might be a problem of the battery or the charger. If possible you should first try this battery in another phone and/or another battery in your phone.
If you have the possibility to charge the battery outside the phone that too would we worth to try.
For me it looks like your battery is empty but I might be wrong.
Flashed it again with a samsung stock rom. Now its staying alive.
Now it notifies me every few minutes that "Charging paused. Voltage too high.".
The phone is not currently connected to charger.
My guess is that the battery has gone bad. Unfortunately i don't have any other batteries or phones that i could test.
I think i have to go and buy a new battery.

Actually, this sounds like the port may be bad. You could try cleaning it... But you'll probably have to replace it.
Hey Folks,
I have a Samsung Galaxy SII (SGH-i777) that I used a couple of years ago. It was my first Android phone and I loved it very much (until corporate made me an iSheep).
The phone was retired to a shoe box for the last 1+ years and I recently dug it up so I could get it set up for my little bro who somehow recently fell on his phone with it in his pocket and shattered the screen (don't ask... I don't get it either).
Anyways long story short -- the phone sat idle for a long time, when I pulled it out it wouldn't boot up at all. Assumed that the battery had discharged so I plugged it in to see if it would start up. The battery logo would intermittently flash on the screen and show a drained battery logo but even letting the phone sit for a day did not provide me any results.
Fast forward 3-6 months. Today I replaced the charging board thinking that there was some issue with the USB connector on the phone that was preventing it from getting power. Once that was done I discovered that I was able to get the phone to boot into Odin mode. Great! No boot, no recovery, but download mode seemed to be better than nothing.
I have tried, in vain, to flash stock firmware to this phone via Odin, and even though all indicators point to it being successful, once I finish the Samsung logo comes up on the screen, goes off and that's it. I can see the 4 LEDs on the buttons at the bottom of the phone flash every 5 seconds as well as a faint flicker on the screen staggered between the LED flashes.
Looking for any further suggestions as to what I may be able to try. I have searched various sources on XDA and other sources but I haven't quite found anything that matches my exact symptoms.
Furthermore, I can't be sure what Kernel/ROM I was last running on this phone. Maybe Siyah kernel, maybe CM 10,1 with Flux kernel. Idk.
Any input is appreciated!
Seems I should mention this other detail --
With the battery in, I cannot get into download mode -- it just states 'Low Battery!! Can't Download!!" This is presumably due to the fact that the battery is completely discharged -- maybe incapable of holding a charge but perhaps this is indicative of a more serious hardware failure.
I'd guess the battery is completely shot.
I bought a replacement battery from here: http://www.ebay.com/itm/111014533334?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
No problems with it.

Very likely --
Since you got me to shift focus here, a quick search is telling me that it won't boot without a battery due to a feedback circuit. This would explain the ability to go into download mode but the lack of boot / flashing LEDs I guess.
Can someone confirm?
If the phone was working normally when it was put away, I would expect it to be working normally when it was pulled it back out. Your story is a little confusing, but did you ever try booting the phone with a fully charged battery? In the circumstances you describe, that would be the first logical trouble shooting step. And if you haven't tried that, then it is still the next logical trouble shooting step. Also, you can't assume that the original battery that you left in the phone is still able to hold a charge. It still may be good, but you can't assume that for testing purposes. Incidentally, the battery should have been pulled from the phone before it was put away.
I do not get any indication that the original battery is actually charging. Charging icon just flashes on the screen briefly in between LED and screen flashes (again, presumably due to the battery being completely dead/incapable of holding a charge since I left it in the phone this entire time).
I guess I'll go ahead and buy another battery and see what happens.
It is my understanding then that this phone will not boot on the charger without battery due to a feedback circuit. Correct?

Even if the battery is good, but fully discharged, it may not charge in the phone. You would have to have an external charger. Phones are not consistent, and many phones probably would charge a fully discharged battery, but I have seen a number of people report that a fully discharged battery would cause the exact same behavior as you report. If it were mine, I wouldn't throw the battery away yet.
If you know anyone with an I777, you could borrow their fully charged battery for a few minutes just to see if your phone will boot.
You are correct that the phone will not boot on the charger when the battery is out, although you should be able to successfully flash firmware through Odin with the battery out, and the computer supplying the power, but still, as far as I know, it will not boot after the flash without a working battery.
The battery was indeed at fault. Ordered a new one on Amazon, popped it in and voila -- we're up and running.
Thanks for the input guys! Much appreciated!
Hey guys,
unfortunately my 3-year old Razr died the other day. Battery has been an issue for the past few months where I had the battery completely drained 2 times but always got the device back to work. This time it's different though.
I shut down the Phone at aprox. 20% Battery to safe it from low charge. I have NEVER flashed a custom rom, the phone is purely stock. The phone wouldn't turn on the next time i tried. Initially , I had zero reaction. Then, I got at least the white LED when charging with the original adapter. Let it charge a few days. The white light would turn off after a few hours but the phone is still dead.
I replaced the battery with another (new) EB20 but still nothing. I bought a wall charger (1A) and still nothing. I even tried direct charging the battery for a few hours and still no effect. Also, every combination of Power+Volume buttons didnt work.
So i bought a factory cable but still didnt get any reaction. When hooked up to a computer via USB i have a "connecting" and "disconnecting" sound. Once the device was detected as OMAP 3340 but couldnt install it. The problem is that I dont even get the phone into fastboot mode.
On my research, I found these posts:
http://forum.xda-developers.com/showthread.php?t=2055839
http://forum.xda-developers.com/showthread.php?t=2047750
I think this will be my last try and option, but i have no experience whatsoever with flashing and I find the description very hard to understand and follow. Is there maybe someone who can explain step by step what there is to install/do and in what order? This would be awesome.
Greets,

A couple of days ago I replaced the battery on my Poco F1, because the phone is 2.5 years old and AccuBattery reckoned it was at 71% health. There were no issues with the phone, only that the battery life wasn’t as good as it once was (it was still running from 100% - 0% battery charge).
I bought the battery from AliExpress (this one to be precise) and the process of switching it out was easy and faultless, as far as I could tell.
The reassembled phone booted up fine and the new battery was at ~ 50% capacity. On the AliExpress listing it said to run the battery flat, which is what I did and it lasted quite a few hours - all good.
I then recharged the phone to full, as stated in the instructions. Regretfully, I interrupted the first recharge a couple of times by unplugging the phone for a few minutes each time. I'm telling you this for full disclosure - I'm unsure if this is likely to have caused the problem that I am now facing.
The fully recharged phone lasted a few hours and then shut itself down, whilst on ~ 70% battery I believe. This was the first time I realised there was a problem. The phone would not turn back on - holding down the power button and/or any combination of volume buttons did absolutely nothing. However, plugging the phone in caused the battery charging screen to appear instantly and subsequently, holding the power button whilst still plugged in would turn the phone on as normal. The phone would then boot up and battery percentage would be at ~70%, as it was when it shutdown (once booted, volume keys work fine). The phone would appear to charge as normal, but whenever I unplugged the phone, it would eventually shutdown on a high percentage after anything from a few seconds up to around an hour.
I thought I must have gotten a dodgy battery, so I took it out and put the original one back in. Now the old battery has all of the same symptoms as the new one – it won’t turn on unless plugged in and randomly shuts down after a period of time. If I manually turn the phone off when unplugged, it won’t turn back on unless it is plugged in. Also, a reboot just shuts it down.
I happened to have a spare charging port board, so I put that in to see if I’d fried something on there, but that hasn’t helped.
I’m tempted to reset the phone to stock (currently running Pixel Experience with TWRP installed) but am worried that it will brick the phone if it tries to reboot during the flashing process. Also, I believe that the fact I can’t force boot into fastboot with volume down/power buttons proves it is a hardware issue?
Any ideas are very welcome.
I think unless you have access to an EDL authorised account it's better to not flash MIUI at this stage. Risk of bricking the device...

Exactly the problem I am going through. It's all started today. I am currently running stock MIUI. It keeps boot looping if I do not plug the charger. But once it's plugged, it will load up normal.

I did flash stock MIUI in the end. Did not brick it, but also did not fix it. The phone now turns off immediately after being unplugged every time. I got myself a black Friday Poco X3 Pro so I'm now selling this phone for parts in UK

It could be a buggy PMIC issue similar to https://forum.xda-developers.com/t/...android-11-0-vayu-bhima.4267263/post-85119331
Third-party batteries are mostly crap and probably the original battery is completely drained and the BMS isn't allowing it to be charged as a safety measure?
